CAPONIZIN'G-TO 0L.

Application filed. March 23, 1915.

To all whom it may concern:

Be it known that I, Soorr K. BURDIN, a subject of the King of Great Britain, and resident of the city of Ottawa, in the'Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Caponizing-Tools, of which the following is the specification.

This invention relates to caponizing tools and the objects of the invention are to provide a tool that will enable the operator to perform the operation with ease, despatch and certainty of successful results. Tools for this purpose at present in use are made straight so that when the operation is being performed the line of vision is obstructed by the tool and actuating hand of the operator which intervenes and throws shad .ows on the organ to be removed thus pro ducing uncertainty and making a large incision necessary, and the object of this 1nvention is to overcome these objections and to provide a tool allowing at all times a clear line of vision to the point of the gripping members and the organ to be removed, thus requiring only a small opening or incision and enabling the operator to make real capons and not slips.

The invention consists essentially of the novel features of construction particularly described and set forth in the following specification and accompanying drawmgs forming part of the same.

In the drawings, Figure 1 is a perspective view of a caponizing tool adapted to be operated by the action of the index finger. Fig. 2 is a perspective view of a caponlzlng tool adapted to be actuated by the thumb action of the operator. Fig. 3 is a section taken through the operating ends of the instruments shown in Figs. 1 and 2.

Like characters of reference refer to like parts in the several drawings.

Referring to the drawings, Flg. 1 represents the improved caponizing tool comprlsing the two levers 10 and 11 plvotally connected intermediate of their ends, one end of each of the said levers being suitably formed as shown at 14 and 15, for gripping and holding the spermatic cord of the organ to be removed, the opposite ends of each of the said levers being offset downwardly to form a hand and finger grip 12 and 13 which may be controlled by a spring 18 or Specification of Letters Patent.

the like if desired, or actuated by the index finger.

In Fig. 2 the tool is adapted to be ac tuated by the thumb action of the operator and to this end the offset end of the lever 11 is bent to form a finger or hand grip 12 while the offset end of the lever 10 is bent at 13 and adapted to be engaged by the thumb.

In the use of the instrument illustrated in Fig. 1, the ends 14 and 15 are inserted in a small incision in the fowl being operated on. The end 14 of lever 10 is placed beneath the organ to be removed, the opposite ofi'sethandle end 12 being held firmly in the hand of the operator while the index finger engages lever 11 at 13, whereupon the opposite end 15 is brought down on 14, thus gripping the spermatic cord of the organ firmly between 15 and 14, when the organ can be removed with absolute success.

It will be observed that the hook shaped end 14 has a plate or pan below it adapted to support the organ being removed, and keep the intestines from interfering with the operation.

It will be seen that by this novel means of construction all obstructions caused by the hand or tool to the line of vision are removed and that lever 10 becomes practically stationary or rigid while lever 11 is being actuated by the index finger, thus enabling the operator in the absence of any obstruction or shadows to perform the operation successfully, even though he be a novice.

The use of the instrument illustrated in Fig. 2 is much the same as that in Fig. 1 except that lever 10 is actuated by the thumb instead of remaining rigid as in Fig. 1. The line of vision however is unobstructed by the use of offset handles 12 and 13 As many changes could be made in the above construction and many apparently widely different embodiments of my invention, within the scope of the claim, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

A caponizing tool comprising a lever having an offset handle portion adapted to be engaged by a plurality of the operators fin- In witness whereof I have hereunto set gers, and having also a hook shaped end my hand in the presence of two witnesses. with a pan below the same and a second lever fulorumed to the first zind being formed SCOTT BURDIN' with an offset finger grip, and having the Witnesses: end shaped to cooperate wlth the end of the JAMES MITCHELL, other lever for'use 1n caponlzlng.
